[Phalaris angusta (Gramineae) causing neurological disease in cattle in the State of Santa Catarina, Brazil.] Phalaris angusta (Gramineae) como causa de enfermidade neurológica em bovinos no Estado de Santa Catarina. Pesquisa Veterinária Brasileira 19(1):35-38. Depto Clínica e Patologia, Centro de Ciências Agroveterinárias, Universidade do Estado de Santa Catarina, Av. Camões 2090, Lages, SC 88520-000, Brazil.
Two outbreaks of spontaneous poisoning in cattle by Phalaris angusta Neês ex Trin. ("aveia louca", "aveia de sangue") are reported in cattle. The outbreaks occurred in the State of Santa Catarina, Brazil, during the winters of 1993 and 1996. In both outbreaks the animals were held in paddocks where P. angusta was a prevalent forage. Clinical sigos in affected cattle included generalized tremors, alertness, hypermetria, ataxia and convulsions. Gross lesions were restricted to the brairi and consisted of gray to greenish discoloration in the thalamus and mesencephalon. The disease was experimentally reproduced in cattle by administration of P. angusta. |
